3.2 Mounting the System in an Equipment Rack
This power system is designed to mount in a 23-inch wide rack having 1-inch or 1-3/4-inch multiple drillings. Refer to System
Application Guide SAG582127000 for overall dimensions. Perform the following steps to mount the power system.
DANGER! The power system is heavy. Use a hoist, battery lift, or other appropriate lifting device to raise and support the
power system during the installation. Take appropriate precautions to avoid injury.
NOTE! Refer to “General Requirements” on page 2 for mounting restrictions and ventilation requirements.
NOTE! The power system consists of a distribution cabinet and module mounting assemblies. The distribution cabinet is
factory connected to the module mounting assemblies. The distribution cabinet with module mounting assemblies is
mounted as a complete assembly.
Procedure
1. Position the power system in the equipment rack.
NOTE! In the next steps, install (orient) the ground washers so the teeth dig into the mounting angles for a secure ground
connection.
NOTE! Compliance with Telcordia GR-1089-CORE requires that prior to mounting the system to the equipment rack:
- All paint must be removed from the front surface of each equipment rack rail where it mates with a shelf-mounting
bracket, so that good metal-to-metal contact can be established between the shelf and rack.
- The shelf-to-rack mating surfaces must be cleaned.
- Electrical anti-oxidizing compound must be applied to the shelf-to-rack mating surfaces.
2. Secure the power system to the equipment rack using hardware as shown in Figure 3.1. Use grounding washers at all
locations. Torque connections to the value indicated in Figure 3.1.

4.2 Jumper Settings on the System Interface Circuit Card
Perform the following procedures to verify the factory settings and/or make the required settings per your site requirements. These
procedures can also be used to make adjustments on a replacement circuit card.
Controller Power Option
This option allows the controller to remain powered if a battery LVD contactor is furnished and it opens. The controller is powered
from the internal “system” bus. Rectifiers and battery are connected to this “system” bus, so the controller is powered both by the
rectifiers and by the battery. A jumper option allows the controller to be powered from the “system side” of a battery LVD contactor
(if furnished) or the “battery side” of a battery LVD contactor (if furnished). Refer to Figure 4.2 for circuit card location and jumper
location.
• Jumper in “No Battery Power” Position: The controller is powered from the “system side” of a battery LVD contactor (if
furnished). Note if a battery LVD contactor is not furnished, the controller is powered by both rectifiers and battery. If a
battery LVD contactor is furnished and opens, the controller is powered by the rectifiers (if functional).
If you lose AC power and your battery LVD contactor opens, the controller will shut down.
• Jumper in “Battery Power” Position: The controller is powered from the “battery side” of a battery LVD contactor (if
furnished). Note if a battery LVD contactor is not furnished, the controller is powered by both rectifiers and battery. If a
battery LVD contactor is furnished and opens, the controller is powered by the battery and the battery will drain. The
controller’s power consumption is 5W.
If you lose AC power and your battery LVD contactor opens, the controller will continue to operate.
Procedure
1. Refer to Figure 4.2 and place the jumper on J4 in the “Battery Pwr” or “No Battery Pwr” position.
